Treatment of fuel waste is not really a difficult problem.

An area less than half a (european) football stadium to contain 45 years of fuel waste for 4 nuclear plants. As of April 2018, there are 449 operable power reactors in the world. That means you need an area as large as 56 football stadiums to contain all the fuel waste in the world. Not exactly an impressive area. A solar park this size would output energy equivalent to less than a 10th of one modern nuclear plant. *EDIT: changed a 1000th to a 10th. It greatly exaggerates the solar capacity, but it doesn't change the point anyway.
